Police investigators told Lima's La Republica newspaper that van der Sloot's bombshell confession came late Monday night when he tearfully admitted that he grabbed Stephany Flores Ramirez by the neck when she began reading articles about him on the Internet.

Joran Van Der Sloot Confesses to Killing Peruvian Woman

"I did not want to do it. The girl intruded into my private life," he told investigators, according to La Republica . "She had no right."

"I confronted her," he continued. "She was frightened, we argued and she wanted to get away. I grabbed her by the neck and I hit her."

Van der Sloot could be charged with murder as early as today.

Dave Holloway, Natalee Holloway's father, told "Good Morning America" today that search teams had been assembled in Aruba in case Peruvian investigators are able to glean any more information about the teenager's 2005 disappearance while on a school vacation.

"He's confessed to this one," Holloway said of Flores' death, "and I'd like for him to tell everyone what happened."

Holloway said he's been closely following the Flores case, calling it "deja vu."

"I would just like to say that you know all the pain and suffering that we've gone through, hopefully justice is served this time," he said.

Holloway also said he believed Beth Twitty, his ex-wife and Natalee Holloway's mother, was the only family member who knew about an alleged extortion plot involving van der Sloot that was under investigation when he was taken into custody for Flores' murder.

A spokeswoman for Twitty said Natalee mother's "heart is with the Flores family, and that they remain in her thoughts and prayers."

"I know they are suffering," Twitty said in statement.

U.S. authorities have issued an arrest warrant for van der Sloot, saying $15,000 was wired to the Netherlands from Holloway's hometown in Alabama in exchange for information about her disappearance and the location of her remains.

"Unfortunately I knew nothing about it," Holloway said. "I think the only person that was involved in this incident was Beth ... the FBI indicated that this was a situation that only the people were involved in it knew."

Van der Sloot to Take Investigators to Scene of the Crime

In Peru, sources told ABC News that van der Sloot will take investigators to the scene of the Flores murder, the Lima hotel where he and Flores were captured on surveillance video walking into his room on May 30. It was the last time Flores was seen alive.

Flores battered body was found three days later, her neck broken. Van der Sloot was extradited back to Peru after fleeing the country for Chile last week. He initially denied killing her.

Peruvian authorities have been careful to document every step of their investigation, videotaping every move including a search of his belongings.

Prior to van der Sloot's reported confession, Peruvian authorities released videos of his interrogation and from the hotel where he brought Flores after a night of drinking and gambling.

In the video of his interrogation, van der Sloot can be seen calmly explaining where he's been and what he's carrying, including a laptop, cash from different countries and photos. He even seemed friendly with the officers on his long drive back from Chile to Lima.

When investigators asked him where his credit cards were, van der Sloot answered in broken Spanish.

"I have those back in my hotel in Santiago," he said on the video. "I went up to my hotel room and I saw these things on the Internet and I had to leave quickly."

The calm demeanor van der Sloot showed on the video was a stark contrast to the stunned, even frightened look on his face as he was paraded in front of a media frenzy upon his return to Lima.

On the hotel surveillance video, released this week, van der Sloot can be seen getting his room key from the front desk. Police said they believe Flores was walking behind him, her back to the camera.

Moments later another camera upstairs captured the two walking into van der Sloot's room.

Van der Sloot was captured on camera leaving the hotel alone four hours later, wearing a different shirt and carrying a bag and a backpack.

Though the hotel management declined to comment on why it took three days to discover Flores, sources told ABC News that van der Sloot had pre-paid for a two-week stay and demanded that no one enter his room.

Van der Sloot Investigated in U.S. for Extortion Plot

U.S. authorities told ABCNews.com that they did not issue a warrant for his arrest in the extortion plot until this week because they lacked sufficient evidence.

The federal extortion investigation began in late April, a spokeswoman for the U.S. Attorney's office in Birmingham said.

On May 10, $15,000 was wired to a Netherlands bank by someone in Mountain Brook, Ala., allegedly in exchange for a promise by van der Sloot to provide information about what happened to Holloway and the whereabouts of her remains.

For several weeks van der Sloot had been on the radar of American officials who, in a criminal complaint released Thursday, said he planned to extort $250,000 from the unidentified victim.

A criminal complaint alleging the extortion was filed Thursday, just days after Flores was found dead and van der Sloot had fled to Chile.

Authorities said their charges were not the result of the Peru death.

"This was completely separate and before the girl was killed in Peru," said Peggy Sanford, spokeswoman for the U.S. Attorney's Office in Birmingham. "This investigation had been going on. It was a complete coincidence and tragedy that the other woman was murdered."

The complaint does not name the person whom van der Sloot was trying to extort, by providing information about Holloway's death, but Sanford suggested, van der Sloot had initiated contact by approaching the alleged victim.

"He extorted, or attempted to extort someone, an individual, in exchange for the location of Natalee Holloway's remains and information about her death. Mr. van der Sloot made efforts to extort someone and get money," said Sanford.

U.S. law enforcement, however, may never get to try van der Sloot for the alleged extortion scam. He arrived in Peru today under armed guard.

"He's going to get a very long sentence in Peru," Black said. "By the time he gets out of jail, if he ever does, this would be a footnote in history."

The lawyer said, however, that the Holloway disappearance could be used "as evidence of proof in Peru," and the Holloway family may ask a Peru court "for a longer sentence because of Natalee's murder."
